The Website Speed Test is a free online performance analysis tool that measures how fast any webpage loads and identifies the specific resources and issues causing slowdowns. Page speed is both a user experience factor and an official Google ranking signal — especially for mobile search where Core Web Vitals scores directly influence rankings.

This tool goes beyond simply measuring load time — it shows you a waterfall chart of all resources loaded, highlights the largest bottlenecks and provides prioritized recommendations for improvement.

How to Test Website Speed

• Enter the URL you want to test
• Click Run Speed Test
• Wait 15–30 seconds for the full analysis
• Review load time, page size, request count and performance grade

Key Metrics Reported

• Load time — total time until the page is fully loaded
• Time to First Byte (TTFB) — server response time
• Number of requests — each HTTP request adds latency
• Page size — total transfer size
• Performance grade — overall letter grade (A–F)

Most Common Speed Issues

• Large unoptimized images (fix with our Image Optimizer)
• No GZIP compression (test with our GZIP Checker)
